Connecting the Router to the WAN 25

To connect the Ethernet cable:

1Turn off power to the router.

2Select the Ethernet cable.

When connecting the router with a PC or a router, use the crossover network cable.

When connecting the router to a hub or a LAN switch, use the straight-through network cable.

3Connect one end of the Ethernet cable to the appropriate Ethernet module on the router.

4Connect the other end of the Ethernet cable to the Ethernet port of the network device.

5Verify the connection by checking that the 100M ETH LED on the top of the router is on.

Connecting the Router to the WAN

Connecting the AUX Port to the Modem

The Router 3000 series routers provide the following WAN ports:

■AUX port (all models)

■Mutiprotocol synchronous/asynchronous serial port (Router 3012, Router 3013, Router 3015)

■ISDN S/T port (Router 3013)

■ISDN U port (Router 3015)

■CT1/PRI port (Router 3016)

■E1/CE1/PRI port (Router 3018)

See Chapter A for illustrations and pinout details of all WAN port cables.

The auxiliary (AUX) port is an EIA/TIA-232-compliant synchronous/asynchronous serial port that is used for remote configuration or dial-up backup. To connect the router to a remote device, a local modem must be connected to a remote modem through PSTN. For the connection method, see Chapter 3. For the AUX port specifications of each router, see Chapter 1.

If the console port fails, the AUX port can also serve as a console port.

To connect the AUX cable:

1Turn off power to the router.

2Plug the RJ-45 connector of the AUX cable into the AUX port of the router.

3Connect the DB-25 or DB-9 adapter of the AUX cable to the serial port of the analog modem.

For pinout details of the AUX cable, see Appendix A.

Connecting the Serial The serial port is usually used to connect the router to DSU/CSU. For the serial port Port to a CSU/DSU specifications of each router, see Chapter 1.

CAUTION: Plugging and unplugging the connectors of the serial port online can damage the router or the remote device.
